How to make an Electric Toothbrush?

Electric Toothbrush is unique among DIYers. Here is a simple design on how to make a battery-powered electric toothbrush.

Here is a design that functions as a control circuit and amplifier to an electric toothbrush motor. The design features an ultra-low-power microcontroller unit (MCU) for generating the appropriate waveforms to the H-Bridge motor driver. The motor driver amplifies the signal that is coming from
the MCU and drives the motor.
